Another of the five soldiers at Joint Base Lewis-McChord charged with killing civilians in Afghanistan last year is having his case sent to a court martial.

The base announced Friday that Pfc. Andrew Holmes of Boise, Idaho, will face trial on murder, conspiracy and other charges. Three other defendants have also had their cases referred for court martial.

The soldiers are accused of killing three civilians in Kandahar Province for sport last year. Holmes is accused of directly participating in the killing of the first victim. Authorities say one of the central figures in the case, Spc. Jeremy Morlock of Wasilla, Alaska, admitted throwing a grenade toward the unarmed man and said Holmes was in on it. Holmes acknowledges shooting at the man but claims he believed he was responding to a genuine threat.

No trial date has been set.
